Description
Technical Field
The invention relates to the technical field of household electrical appliances, in particular to a filtering component for juice extracting equipment and the juice extracting equipment with the filtering component.
Background
Slow juice extraction devices have been popular for home use. However, the filter net for filtering residues in the existing juice extractor apparatuses is generally a mesh drum formed of a stainless steel filter net provided with mesh holes. The filtering holes are easily blocked by food materials during juicing, so that the juicing efficiency is reduced. Furthermore, cleaning the mesh drum after the juice extraction process is completed is a very complex task, typically requiring repeated brushing of the mesh with a brush. The above-mentioned drawbacks lead to a reduced user experience.
Furthermore, when fruit juice without fruit particles and fruit juice containing fruit particles need to be extracted, two different mesh drum fittings provided with a small mesh and a large mesh, respectively, need to be used. Such operation is disadvantageous to the user experience and increases the production costs of the device.
Disclosure of Invention
In order to solve at least one aspect of the technical problems described above, the present invention provides the following solutions.
The present invention provides a filter assembly for a juice extractor apparatus, the filter assembly comprising: a cylindrical first fitting, on a circumferential side wall of which at least two sets of first grooves are provided in a longitudinal direction or at an angle to the longitudinal direction, at least a part of the first grooves forming a first through space penetrating the circumferential side wall of the first fitting in a radial direction; and a cylindrical second fitting, the first fitting being adapted to couple with the second fitting such that a circumferential sidewall of the first fitting is received inside the second fitting; wherein: at least two sets of first protrusions protruding in a radial direction from an inner surface of the circumferential side wall of the second fitting are provided on the circumferential side wall of the second fitting in a longitudinal direction or at an angle to the longitudinal direction, the first protrusions having a shape complementary to the first groove such that the first protrusions are received in a form-fitting manner within the first groove; and changing a gap size between an interface of the first boss and the first groove by correspondingly coupling the first boss of a different set with the first groove of a different set when the first fitting is coupled with the second fitting.
Therefore, by arranging the circumferential sizes of the first protruding parts of different groups and the first grooves of different groups, juice with different tastes can be obtained by using the same filter assembly. For example, when the first fitting is coupled with the second fitting, the juicing material of different particle sizes can be passed through the filter assembly by rotating the first fitting or the second fitting about the longitudinal direction of the shaft center of the cartridge such that the different sets of first protrusions correspond to the different sets of first grooves, thereby allowing the gap size between the interfaces of the first protrusions and the first grooves.
Thus, the manufacturer of the juice extractor device does not need to provide additional filter mesh devices for different taste requirements, on the one hand reducing the costs of production, transportation, packaging etc., and on the other hand reducing the additional expenditure for this by the user.
In one embodiment, at least a portion of the first boss protrudes from an inner surface of the circumferential sidewall of the first fitting in a radial direction when the first fitting is coupled with the second fitting.
Therefore, the protruding part protruding out of the inner surface of the circumferential side wall of the first accessory can be tightly matched with the screw rod of the juicing device, and juicing materials can be better squeezed and ground.
In one embodiment, the first projection does not protrude from an inner surface of the circumferential side wall of the first fitting in a radial direction at an upper portion of the filter assembly; in the middle of the filter assembly, the first protrusion protrudes from the inner surface of the circumferential side wall of the first fitting in the radial direction, and the size of the inner surface protruding from the circumferential side wall of the first fitting becomes gradually smaller toward the lower portion of the filter assembly in the longitudinal direction.
Thus, the first protrusion does not protrude from the inner surface of the circumferential side wall of the first fitting at the upper portion of the filter assembly, so that the first groove on the first fitting forms a filter groove at the upper portion through which juice is easily squeezed; in the middle part of the filtering component, the protruding part protruding out of the inner surface of the circumferential side wall of the first fitting can be tightly matched with a screw rod of the juicing equipment, so that the juicing material can be better squeezed and ground, and the section is a main section for squeezing and grinding the juicing material; at the lower part of the filter component, the first protruding part protrudes from the inner surface of the circumferential side wall of the first fitting, and the size of the first protruding part gradually becomes smaller to completely disappear, so that the section can be completely attached to the screw rod of the juice extracting device, and better squeezing and grinding effects on juice extracting materials are obtained.
Further, the first fitting and the second fitting are coupled in one of the following ways: the first fitting is adapted to slidingly couple with the second fitting along a longitudinal direction; the first fitting is adapted to slidingly couple with the second fitting along a direction that is angled from a longitudinal direction; the second fitting is adapted to be coupled to the first fitting in a multiple component assembly.
Therefore, the filter assembly can realize the coupling of the first fitting and the second fitting in various modes, so as to adapt to the requirements of different users and operation occasions.
In one embodiment, a plurality of second grooves are provided on the circumferential side wall of the second fitting in the longitudinal direction or at an angle to the longitudinal direction, at least a portion of the second grooves forming a second through space penetrating the circumferential side wall of the second fitting in the radial direction.
Thereby, juice passing through the gap between the interface of the first protrusion and the first groove can be easily discharged out of the filter assembly through the second penetration space.
In one embodiment, the first boss is disposed on a circumferential side wall of the second fitting between two adjacent ones of the second grooves of the second fitting.
Thus, juice passing through the gap between the interface of the first protrusion and the first groove can be discharged to the second grooves on both sides, resulting in a better juice discharging effect.
In one embodiment, the first groove tapers in size in the circumferential direction along the longitudinal direction toward the upper portion of the filter assembly to guide the first boss into the first groove along or at an angle to the longitudinal direction.
In one embodiment, the first groove tapers in size in the circumferential direction toward the interior of the filter assembly in the radial direction to guide the first boss into the first groove in the radial direction.
Thereby, the first protrusion may be guided into the first groove.
In one embodiment, the circumferential side wall of the first fitting is provided with a plurality of second protrusions protruding from the inner surface of the circumferential side wall of the first fitting in the radial direction in the longitudinal direction or at an angle to the longitudinal direction; the second projection projects in a radial direction from an inner surface of the circumferential side wall of the first fitting in a size that becomes smaller toward a lower portion of the filter assembly in the longitudinal direction.
Thereby, the tightness between the circumferential side wall of the first fitting and the screw of the juicing device can be improved, and the juicing efficiency can be improved.
In one embodiment, the interface of the first groove on the circumferential side wall of the first fitting is inclined towards the interior of the first fitting.
Thereby, the first groove has a smaller size in a direction toward the inner side of the first fitting, and the filtering effect of the filter assembly can be improved. At the same time, a certain accommodation space is formed in the outer side direction of the first groove towards the first fitting, and the first groove can be allowed to slightly deform to allow juice to enter.
In one embodiment, a third protrusion protruding in a radial direction from an outer surface of the circumferential side wall of the first fitting is provided on the circumferential side wall of the first fitting in the longitudinal direction or at an angle to the longitudinal direction; the second fitting circumferential side wall is provided with a groove on the upper surface for receiving the third boss.
Therefore, the first fitting and the second fitting cannot rotate relatively after being coupled, and accordingly the filtering assembly can guarantee the filtering effect when the screw rod rotates.
In one embodiment, when the first fitting and the second fitting are in a first coupled state, a gap exists between the interface of the first boss and the first groove; when the first fitting is rotated about the longitudinal axis of the first fitting by a predetermined angle relative to the first coupling state and is in a second coupling state with the second fitting, a gap between the interface of at least one set of first protrusions and at least one set of first grooves changes.
In one embodiment, when the first fitting is in the second coupling state with respect to the first coupling state, a gap existing between an interface of one set of the first protrusions and one set of the first grooves becomes larger, while a gap existing between an interface of another set of the first protrusions and another set of the first grooves becomes smaller.
Thus, by providing different sets of the dimensional differences between the first bosses and the first grooves, the size of the gap between the first bosses and the first grooves can be adjusted.
In one embodiment, the gap size between the interfaces of the first fitting and the second fitting can be changed by rotating the first fitting a predetermined angle relative to the second fitting and then coupling.
A further aspect of the invention provides a juice extractor apparatus comprising a filter assembly as claimed in any preceding claim, wherein: the filter assembly is arranged around the screw of the juicing device, is matched with the screw, presses and grinds juice squeezing materials, and separates juice squeezed from residues.

Example 1
As shown in fig. 4, the filter assembly of the present invention is generally cylindrical. When being applied to juice extractor, this filter component sets up around the screw rod, when the screw rod rotates, squeezes juice extracting material between the inner wall of screw rod and filter component, grinds. The extracted juice is discharged through holes in the circumferential side wall of the filter assembly, while the residue is discharged from discharge holes provided in the bottom of the filter assembly.
The filter assembly of the present invention includes a first fitting 100, a second fitting 200. Wherein the first fitting 100 is coupled into a filter assembly by slidingly entering the interior of the second fitting 200 in a longitudinal direction. The filter assembly of the present invention will be described in detail below.
First fitting
As shown in fig. 1, the first fitting 100 is substantially cylindrical, wherein the cylinder formed by the first fitting has a gradually decreasing size in the longitudinal direction, thereby forming a well-shaped fit with a screw (not shown in the figure) of the juice extractor device.
A plurality of first grooves 104 are provided on the circumferential side wall 106 of the first fitting 100 in the longitudinal direction, at least a part of the first grooves 104 forming a first through space penetrating the circumferential side wall 106 of the first fitting 100 in the radial direction. As can be seen from the figure, the bottom 107 of the first groove 104 has a larger circumferential dimension, while the top 108 of the first groove 104 has a smaller circumferential dimension. More specifically, the first groove 104 tapers in size in the circumferential direction toward the upper portion of the filter assembly along the longitudinal direction, and as such, is capable of guiding the first boss 204 (described in detail below) into the first groove 104 along the longitudinal direction.
In one embodiment, the first groove 104 tapers in size in the circumferential direction toward the interior of the first fitting in the radial direction to guide the first boss 204 into the first groove 104 in the radial direction.
In one embodiment, the interface of the first groove 104 on the circumferential sidewall 106 is sloped toward the interior of the first fitting 100. The first groove 104 has a smaller size in a direction toward the inside of the first fitting 100, and can improve the filtering effect of the filter assembly. Meanwhile, a certain receiving space is formed in the outer side direction of the first groove 104 toward the first fitting 100, and a minute deformation of the first groove 104 can be allowed to allow juice to enter.
In one embodiment, the first grooves 104 are arranged in groups, as shown in the figures, with 4 groups of first grooves 104 symmetrically disposed on the circumferential side wall 106 of the first fitting 100. Each set of first slots 104 is separated by a larger wall section 103, while adjacent first slots 104 of a set are separated by a smaller wall section 109.
In one embodiment, on the circumferential side wall 106 of the first fitting 100, a second protrusion 101 protruding from the inner surface of the circumferential side wall 106 is provided extending downward in the longitudinal direction from the upper top 105 of the first fitting. The height/size of the second boss 101 protruding from the inner surface of the circumferential side wall 106 is larger near the upper portion of the first fitting, whereby the fitting relationship of the inner surface of the first fitting 100 to the screw can be improved. The height/size of the second boss 101 protruding from the inner surface of the circumferential side wall 106 becomes gradually smaller downward in the longitudinal direction.
A plurality of third protrusions 102 are provided on the outer surface of the circumferential side wall 106, adjacent to the top 105 of the first fitting 100, in the longitudinal direction. The height/size of the third protrusion 102 protruding from the outer surface of the circumferential side wall becomes gradually larger downward in the longitudinal direction. Preferably, the third protrusion 102 extends only a short distance in the longitudinal direction. However, it should be understood that the third boss 102 is configured to couple with a correspondingly disposed recess 202 (described in detail below) on the second fitting 200 such that the two are secured to one another, and thus may be shaped and sized in a variety of ways, as the invention is not limited in this regard.
The bottom of the first fitting 100 is formed with a stepped ring 110 that is abrupt in size with respect to the circumferential sidewall 106. The stepped ring 110 is adapted to form-fit with the second fitting 200.
Second fitting
As shown in fig. 2, the second fitting 200 is substantially cylindrical. And the second fitting 200 is larger in size than the first fitting 100 so that the circumferential side wall of the first fitting 100 can be accommodated inside the second fitting 200.
As can be seen from fig. 2, the circumferential side wall 206 of the second fitting 200 is provided with a plurality of first protrusions 204 protruding in the radial direction from the inner surface of the circumferential side wall of the second fitting 200 in the longitudinal direction.
As more clearly seen in connection with fig. 3, the first bosses 204 may be arranged in groups, the first set of first bosses 206 may be 4, and the second set of first bosses 206' may be correspondingly arranged to be 4.
In one embodiment, a plurality of second grooves 201 are provided in the longitudinal direction on the circumferential side wall 206 of the second fitting 200. In this way, the extracted juice can be discharged from the second tank 201. It should be understood that the figure shows only one embodiment of the second tank 201, and that the specific shape of the second tank 201 is also various as long as it can meet the juice discharge requirement.
The first protrusions between different groups may be separated by a larger wall section 207, the first protrusions between the same groups being arranged inside the smaller wall section 203.
It should be appreciated that the first boss 204 provided on the second fitting 200 is a form fit with the first slot 104 on the first fitting 100. Thus, the size of the first boss 204 is also tapered in the longitudinal direction toward the top of the filter assembly.
Further, inside the circumferential side wall 206 of the second fitting 200, a groove 202 corresponding to the third boss 102 of the first fitting 100 is provided in the longitudinal direction from the top 205.
Referring to fig. 3-8, it can be seen that the first projection 204 does not protrude from the inner surface of the circumferential side wall 106 of the first fitting 100 in the upper portion of the filter assembly, such that the first groove 104 of the first fitting 100 forms a filter groove in the upper portion through which juice is readily extracted.
In the middle of the filter assembly, the first protruding portion 204 protrudes from the inner surface of the circumferential side wall 106 of the first fitting 100, and the protruding portion can be tightly matched with the screw rod of the juicing device, so that the juicing material can be better squeezed and ground. Thus, the middle section of the filter assembly is the main section where the juice material is pressed and ground.
At the lower part of the filter assembly, the first protruding part 204 protrudes from the inner surface of the circumferential side wall of the first fitting, and the size of the first protruding part gradually becomes smaller to completely disappear, so that the section can be completely attached to the screw of the juice extracting device, and better squeezing and grinding effects on juice extracting materials are obtained.
Further, as can be seen from fig. 3 and 5, the first protrusion comprises two sets 206, 206' having different circumferential dimensions. The first grooves 104 in the respective first fittings 100 also correspondingly have different circumferential dimensions.
For example, in one embodiment, a set of first bosses 206 have a circumferential dimension of approximately 3mm, and a corresponding set of first slots 104 may have a circumferential dimension of approximately 3.5mm, such that the resulting gap has a circumferential dimension of approximately 0.5 mm; while the other set of first protrusions 206' have a circumferential dimension of approximately 2.5mm, the corresponding other set of first grooves may have a circumferential dimension of approximately 3mm, such that the resulting gap has a circumferential dimension of approximately 0.5 mm.
Thus, the filter assembly in the first coupling state has a smaller gap so as to meet the requirement of squeezing fruit juice without fruit particles.
For example, in another embodiment, one set of first bosses 206 have a circumferential dimension of approximately 3mm, while another set of first slots having a circumferential dimension of approximately 3mm are coupled thereto, such that the resulting gap is approximately closed; meanwhile, the other set of first protrusions 206' may have a circumferential dimension of approximately 2.5mm, and the corresponding coupled set of first grooves 104 may have a circumferential dimension of approximately 3.5mm, such that the resulting gap has a circumferential dimension of approximately 1 mm.
In this manner, the filter assembly may be placed in the second coupled state by rotating the first fitting 100/second fitting 200 about the longitudinal axis to a particular angle and then slidingly coupling in the longitudinal direction. In this second coupling state, the dimensions of the respective sets of gaps are changed compared to the first coupling state. And more specifically, at least one set of gaps is enlarged.
In a typical embodiment, as shown in the drawings of the present invention, the first grooves 104 and the first protrusions 204 are symmetrically disposed along the circumference of the filter assembly, and the opposite sets of the first grooves 104 and the first protrusions 204 have the same circumferential dimensions, so that when it is required to meet the juice extraction demands of different tastes, it is only necessary to rotate the first fitment 100 by substantially 90 degrees with respect to the second fitment 200 and then slidingly couple in the longitudinal direction, thereby obtaining the filter assembly having different gaps.
The above embodiments are merely illustrative modes, and it should be understood that the present invention is not limited thereto. One skilled in the art can select the appropriate modulus of the circumferential dimension to achieve different combinations of gap sizes.
As shown in fig. 5, the first protrusion further protrudes from an inner surface of the circumferential sidewall of the first fitting 100. And the first groove of the first fitting is formed with accommodation spaces 300, 301 at portions toward the outside of the circumferential side wall.
Fig. 6 shows a top view of the filter assembly, wherein section A-A is a cross-sectional view along the oppositely disposed second protrusions 101 and section B-B is a cross-sectional view along the oppositely disposed first grooves 104.
Fig. 7 shows a view of section A-A. It is clearly visible that the second boss 101 terminates at a certain distance from the bottom of the filter assembly, while the upper portion of the first boss 204 does not protrude from the inner surface of the circumferential side wall of the first fitting 100. Thus, the upper portion of the first tank 104 forms a filter tank adapted to allow the expressed juice to pass therethrough.
Fig. 8 shows a view of a section B-B. The upper portion of the first boss 204, which is clearly shown therein, is substantially flush with the inner surface of the circumferential side wall of the first fitting 100, the middle portion of the first boss 204 protrudes from the inner surface of the circumferential side wall of the first fitting 100, and the height/size of the protrusion becomes gradually smaller toward the bottom of the filter assembly.
More specifically, in the upper part of the filter assembly, the first projection 204 does not protrude in the radial direction from the inner surface of the circumferential side wall 106 of the first fitting 100; in the middle of the filter assembly, the first boss 204 protrudes from the inner surface of the circumferential side wall 106 of the first fitting 100 in the radial direction, and the size of the inner surface protruding from the circumferential side wall 106 of the first fitting 100 becomes gradually smaller toward the lower portion of the filter assembly in the longitudinal direction.
Thus, at the upper portion of the filter assembly, the first projection 204 does not protrude from the inner surface of the circumferential side wall of the first fitting, so that the first groove 104 on the first fitting 100 forms a filter groove in the upper portion through which juice is easily extracted; in the middle of the filter assembly, the protruding part protruding from the inner surface of the circumferential side wall 106 of the first fitting 100 can be tightly matched with the screw of the juicing device, so that the juicing material can be better squeezed and ground, and the section is the main section for squeezing and grinding the juicing material; at the lower part of the filter assembly, the first protrusion 204 protrudes from the inner surface of the circumferential side wall 106 of the first fitting 100, and the size thereof gradually becomes smaller to completely disappear, so that this section can be completely attached to the screw of the juice extracting apparatus, and a better squeezing and grinding effect on the juice extracting material is obtained.
